This code requires the variable `_paq` to be set somewhere, but we never
set it.
In the past Decide Madrid added some custom JavaScript using this code.
However, in CONSUL we're using Ahoy to track events, and we don't have
any documentation about adding custom JavaScript to use piwik nor we've
got any other piwik integration.
The `removeCookie` function is never called, and the `initialize`
function doesn't do anything. The only functions we use here are
`getCookie` and `saveCookie`.
The `initialize` functions don't need to return anything, since their
returned value is never used.
Returning false is a common practice in jQuery to stop an event, but in
plain JavaScript methods it doesn't have any side effects.
Internet Explorer 9 was released eight years ago. Besides that, we don't
really support IE8 anyway, since we show a popup to IE8 users saying
we don't support it, we haven't maintained the IE8-specific CSS file for
years, and we don't test our JavaScript against IE8.
The code `where(id: ids)` is equivalent to `where(id: ids.uniq)`.
Since Rails 5 uses `distinct` instead of `uniq` and in most cases where
we use `uniq` with `pluck` we should simply remove the `uniq` call (as
done in this commit), we're also removing the `Rails/UniqBeforePluck`
rubocop rule.
For performance purposes, we need to find bottlenecks in our
application. Optimizing the performance of small methods doesn't make
the application faster.
I've kept a few cops because applying these ones IMHO make the code
easier to read.
These are rules we were already applying.
We've excluded the `factories` folder for some rules because there's a
factory defining a `context` attribute, which rubocop thought was the
`context` RSpec keyword.
We use staging and preproduction environments, which are not valid by
default.
This rule is useful because misspelling the name of an environment might
otherwise go unnoticed.
The Rakefile and config.ru files are now included by default, and the
behaviour of `Include` changed in Rubocop 0.56.0 (see rubocop's pull
request 5882) so now it **only** includes the files defined there, while
in the past it included those files in addition to the default files.
